Introduction to the technology and characteristics of laser cutting

Customers who have used laser cutting technology know that laser cutting processing technology is a kind of technology that uses the laser beam to continuously move on the surface of the parts. The laser beam in this kind of work has good guidance and good correlation. Its cutting capacity is good and dense. The following is a specific introduction to laser cutting processing.

1. Characteristics of laser cutting:

1. The cutting quality is high-quality and fine.

The laser beam used by this type of laser equipment for cutting can be focused on a very small light spot, so that the laser cutting machine can reach a very high power, so the cutting speed is fast, the precision is very high, and it can also ensure that the workpiece will not be deformed.

2. Strong adaptability and high sensitivity.

This cutting method uses hot cutting technology. When cutting, the affected area is very small and will not have a large-scale impact. Another advantage is that it can process some non-metals, of course, this is also something that other laser cutting equipment cannot do.

3. It has high energy and can control the change of its density at will, and can also perform local operations.

This type of laser has good control performance, and can control the running trajectory of the laser cutting machine at will, and can cut any hard material accordingly. With these small accessories, we can also complete the cutting locally.

2. There are several laser cutting processes:

1. Melting cutting is to irradiate the laser incident light into the plate at a high speed. When the laser power reaches a certain critical value, the local area will melt, thereby achieving the cutting effect.

2. Vaporization cutting uses a high-power density laser to heat the processed material to avoid the slag burrs formed by melting due to heat conduction. Part of the material evaporates and disappears, and the edge is more beautiful.

3. Oxidation cutting refers to the thermal processing produced by blowing oxygen into the nozzle to ignite the laser, and the oxygen undergoes a violent chemical reaction; for brittle materials that are easily damaged by heat, the laser beam can be heated and cut at high speed, resulting in a large thermal gradient in the area, severe mechanical deformation, and cracking of the material, also known as controlled fracture cutting.
